Air Pump

ABSTRACT

An air pump having a rotatable chamber in simultaneous communication with a valve and a switch during inflation and deflation of an inflatable device. The air pump housing has a rotatable knob connected to a rotatable chamber. The rotatable chamber has a ramp bisecting the rotatable chamber into a primary compartment and a secondary compartment. During inflation, the rotatable chamber is in communication with a valve and the port of the secondary compartment diverts the airflow from an opening of the rotatable knob in a direction into the inflatable device when the rotatable chamber is rotated to a primary position. During deflation, the rotatable chamber is in communication with a valve and a port of the primary compartment diverts the airflow out of the inflatable device, whereby, the airflow is exhausted through an opening of the rotatable knob when the rotatable chamber is rotated to a secondary position.

BACKGROUND OF THE INVENTION 1. Field of the Invention

This invention relates, generally, to an air pump. More particularly, it relates to an air pump having a multi-functional rotatable chamber having a cam that activates a micro switch to power on and off the motor of the air pump, a ramp bisects the rotatable chamber into a primary compartment that diverts the flow of air in a direction into the inflatable device and a secondary compartment that diverts the flow of air out of the inflatable device, and a mode that seals air within the inflatable device.

2. Background Art

Currently, air pumps are used to inflate and deflate a variety of inflatable devices including, but not limited to, an air mattress, a bounce house, a chair, a cushion, a yard inflatable, or an inflatable prop. These air pumps are installed in the inflatable device and draw air in from one end and discharge air from another end into the inflatable device. Generally, when these inflatable devices need to be deflated, the motors are stopped, the pump is removed, and the air exits by the pressure generated by the collapsing inflatable device. This can be time consuming and does not completely deflate the inflatable device, requiring a user to manually compress the inflatable device to push the remaining air out of the inflatable device.

In some instances, the air pump discharge is removed from the inflatable device and the air pump intake is connected to the inflatable device to draw air out of the inflatable device. There is a need for an air pump that automatically engages when the control is diverted to either the intake or discharge mode so that a user can easily and quickly control the air flow either into or out of the inflatable device. More particularly, when the air pump is turned to an off position the pump motor is off and the air pump automatically seals the inflatable device so that air cannot discharge from the inflatable device.

Conventional air pumps on the market produce high levels of noise generated by the motor and by the airflow. Many inflatable devices such as bounce houses and yard inflatables are kept inflated by the air pump for hours at a time. It is more desirable for an air pump to operate more quietly as to not be a disturbance to surrounding areas. Thus, there is a need for an air pump having a labyrinth of air passages and a plurality of baffles to decrease the noise generated by the motor and by the air flow.

However, in view of the prior art considered as a whole at the time the present invention was made, it was not obvious to those of ordinary skill in the pertinent art how the identified needs could be fulfilled.

SUMMARY OF THE INVENTION

The long-standing but heretofore unfulfilled need for an air pump having a rotatable knob with an opening having a plurality of baffles configured to deflect the flow of air to muffle the sound created by the flow of air. The rotatable knob is connected to a rotatable chamber. The rotatable chamber has a ramp bisecting the rotatable chamber into a primary compartment having a primary port and a secondary compartment having a secondary port. During inflation, an end of the rotatable chamber is in communication with a valve and the port of the secondary compartment diverts the flow of air from an opening of the rotatable knob in a direction into the inflatable device when the rotatable chamber is rotated to a primary position. During deflation, an end of the rotatable chamber is in communication with a valve and a port of the primary compartment diverts the flow of air out of the inflatable device, whereby, the airflow is exhausted through an opening of the rotatable knob when the rotatable chamber is rotated to a secondary position. An end of the rotatable chamber has a recess. When the recess is positioned over the valve, the ports of the primary and secondary compartment are both closed and the valve covers the valve openings to form a seal to retain air within the inflatable device. The rotatable chamber has at least one protrusion located on an outer perimeter surface of the rotatable chamber. The at least one protrusion engages a switch that applies power to the motor. The motor rotates the fans that generate the airflow for inflation and deflation, which also includes improvements that overcome the limitations of prior art air pumps, is now met by a new, useful, and non-obvious invention.

The novel air pump has a housing. The housing has a compartment with a primary chamber. The housing has a motor housing retaining a motor connected to at least one fan blade.
